Starting my first restoration of a early 2000 Mirra Air .. Not the most exiting bike compared to some of the gear on here but will be nice when done ..
Picked the bike up on Wednesday one thing I did notice was how heavy the bike is when loading in the boot ..
The bike can be best described as tatty but functional I think if it was a motorbike it would be classed as a rat bike ..
The bike as far as I can see is very well made and all the parts look serviceable.
I have most the tools and stuff to restore things as I have restored 4 motorbikes so this should not be too much of a problem but saying that if anyone has any experience on these bikes the help will be appreciated ..
The plan is to keep the costs in check and not get carried away and restore the original parts rather than getting carried away on eBay etc .. I will aim to make it look like new in the original colours ...
First quick questions is there a company that sell the decals ??
I will post up a few pictures and keep posting updates ...
-
Ignore the dumb question spotted the sticky for dels decals :P
-
Any pics of the bike? Ive got a bit of a soft spot for turn of the century Haro's.
-
Let's see some pics mate we need more build threads on here
-
I wouldn't mind seeing this too ::)
-
I wanna see this bike 8)

Hi Guys here she is .... rough around the edges but all there and serviceable ...
The intention is to restore the on a budget of £50 .... :LolLolLolLol:

Wheels are in good nick need a clean and the spokes could do with a polish ..
-
I like it, sturdy looking machine that :2gunsfiring_v1: screaming kneesavers. ...... and mabe different tyres

Like these primo v monsters f.ex ->http://bmxmuseum.com/forums/viewtopic.php?pid=3886904#p3886904 ....the decals kinda boring, but what the fook, it's a Dave Mirra. :slayer:
-
Looks good as it is from the photo's. 8) Strip and a clean could be suffice. :daumenhoch:

They hide the truth mate ... The paint is rough ..
I have made some progress this week had an afternoon in the garage I managed to get the decals off the bike they are knackered but could be copied I think this is going to be the expensive part of the build .. Under the decals the paint was new sort of gave me the boost of energy to get on with it I can see what the bike could be ..stripped most the paint from the frame keeping in mind my tight budget I did this by hand wishing I had taken it to the shot blaster after 2 hours ..
Will post up a few pictures when I get the laptop out ...
Just a quick couple question for anyone who can help what size is the bottom bracket bearing on these bikes looks like 19mm and can you replace individual spokes to re spoke a wheel the spokes ain't that bad but for £8 for a set it will make a big difference to the bike ..
Kit list of parts needed
Head bearings
Wheel ball bearings
Gyro cables top and bottom
Front brake cable
Tyres tubes and tape
Bottom bracket bearings and covers
pedals
Brake blocks
Need to get all this for 50 quid :slayer:

Post up a wanted ad. :daumenhoch:

1) bearing - Yeo, should be American bottom bracket, 19 mm bearing size. ... I think :D
2) decals- have alook, could be the set you need -->http://bmxmuseum.com/forums/viewtopic.php?id=400240 .....in case our own decal mäster del aint got a set
3) spoke individually - sure you can respoke individual spokes. Looks You need Spokes 2.0mm straight gauge ( https://knowyourbike.com/haro/mirra-540/2000 )
Edit: about 1) yep should be 19 mm, äs i've seen a 1999 Model with 19mm (http://bmxmuseum.com/bikes/haro/63623 darkian's) and a 2003 also running 19mm (http://bmxmuseum.com/forums/viewtopic.php?id=230792 wired's resto (post #25) )

Thanks guys .. those builds really are top work gives me ideas for this build ...
Here's a bit of a close up of the frame ... just in case the picture hid the real state of the bike but for £20 what can you expect ...
[attachment=1]
Quick update
painted the bar clamp with Halfords satin which looks near to the original finish used a thin coat of etching primer on a well degreased surface, then thin coast of satin .. looks pretty good ... also prepped and painted the bolts with "plasticote" chrome they look ok I might replace these at a later date with zinc coated of polish .. the bolts look allright at a glance ..
[attachment=2]
Made a start on the frame I could have taken this down the bead blasters but in the spirit of this built I am prepping by hand .. I like the wealds and general quality of the frame it really is well made ... the frame has a few small dings nothing to get upset about I was thinking of polishing the frame but the dings will show if I paint it I can "hide" them ...
[attachment=3]
Starting to get into this now ... will crack on this week as not so busy with work etc ...
Cheers

I had a good go at the frame this evening was tempted to start the process of polishing but thought I would stick to the plan anyway I gave it a bit of a trial run with the "BMW Jet black" ...
[attachment=1]

Looking like it's coming together well for £20 mate.
As said above, if you're on a tight budget bang up a wanted list of exact parts (19mm BB bearings for instance) and I'm sure people will have stuff :daumenhoch:
-
thanks again I will put a list on the wanted page ... I saved the gyro and bottom cable ..
Had a "working from home" day today with the kids at the child minders and the Mrs at work ...
I finished prepping the frame and got the etching primer on will blow a coat of black on it later after it has "baked" in the sun good job the mrs is at work .... bit like putting parts in the dish washer :knuppel2:
[attachment=1]
-
Another problem solved ... the sprocket has a nice design on it my sprocket if rough and will need painting ...
I was racking my brains on how to get this back on the painted sprocket easy answer get a sign writer on the job ... my dad retired years ago but can still sign write when needed ... only cost me a few tins of beer ...
this is the original design

Can't beat a dishwasher for cleaning parts. ;D :daumenhoch:

Bit more of an update ...
I put a coat of black on later this afternoon which took a whole can of paint I needed to get another coat on found a tin of Peugeot Graphite grey which will do as a base coat I am fatting it back anyway ... sort of growing on me the graphite idea I might see if Halfords have a really dark graphite near black ...
[attachment=1]
Pretty much finished the back wheel as well
[attachment=2]
-
nice to see the progression on the Mirra :daumenhoch: to 'simply' go for the sprocket design repaint, pretty wild
....concept of that drying rack really takes balls :LolLolLolLol:
-
Today I had to go to work so not much progress had a go at stripping the forks have my first real problem ..
[attachment=1]
the head bearing has a golf ball effect can you get replacements without replacing the frame part ?? be a shame to have to start knocking the frame about ... if anyone has this part please let me know
cheers
paul
-
Is it just the bearing race you need?
-
I'm loving this build ... takes me right back to doing bikes just like this 5 years ago :-)
I should be able to help out on some parts :daumenhoch:
-
According to http://www.bikepedia.com/QuickBike/BikeSpecs.aspx?year=2000&brand=Haro&model=Mirra+540 ...it would need a "1 1/8" threadless Aheadset SB-1". So if the thing on the pic is all that needs to replaced, it seems what you Need is something like a "Aheadset Bearing Cone/Race for 1-1/8" Headsets". (Like this http://www.ebay.com/itm/Aheadset-Bearing-Cone-Race-for-1-1-8-Headsets-/301550848643)
Hope i'm right..... :buck2: ....... Ed'll know anyhow :daumenhoch:
-
Hi guys its only the bit in the picture that I need the "cups" in the frame are good ...
I will replace the races as well as they are out ...
I can "knock" the old one off before I start painting the forks ...
Got the top coat on the frame today will get a pic across later ...
All I need now is the decals to finish the frame ....
-
I went for a black pearlescent paint in the end you cant quite see it in the pictures but looks good ...
Decals and clear coat and its done ...

If anyone has a spare bottom head set "thing" please let me know drink in it ... :D

I managed to get a bit of garage time this weekend made some good progress ...
After taking the wire wheel to the bars they looked good without paint so decided to polish rather than re paint with the chain stays polished and the bottom wheel mount of the forks polished it will look good .. if for any reason I don't like it I can key the metal and paint in the future ... will also polish the seat post ...
Come up ok using the "mops" on the drill I will finish on a bench polisher when I go round my mates workshop ...
[attachment=1]
Next up after the dust settle get a clear coat on the frame this was a bit of a nightmare the paint would not come out right seemed to either go on to thin and look satin or go on and leave runs ... maybe the heat causing to paint to dry to quick the results were not good left it over night in the morning went over the frame with 1200 to 2000 wet and dry to get the curtains out ... gave it a blow over but ran out before I could finish the whole frame ... looks ok but will need flatting back and a final clear coat ...
[attachment=2]
Starting on the seat post and cranks today ...
The bike is going to look really nice so I have decided to get all the bolts etc re chromed or plated it will not cost the earth and will really finish the bike ... I use a chap in Bristol called Nick from "Reality Motor Works" he has done all the plating and coating for my Motorbike restorations does top work ...
Off to custom Riders this week to get all the new parts ...
Cheers
Paul
-
Nice work and it's always great popping into CR :daumenhoch:
-
Not a great deal to add for last week
I did get over my mates workshop on Friday to polish a few bits they have come up nice they have not come up "mirror" have a sort of brushed finish which looks cool ...
[attachment=1]
I did manage to get a reasonable clear coat on the frame still needs a bit of cutting back here and there but looks a whole lot better than it did ... the trick with Halfords clear coat is warm the can but spray in a cool place as the paint dries quick ...
[attachment=2]
Painted the sprocket and the BB cups did the cups in a met blue small detail but when in the frame they look cool ...
[attachment=3]
Off to custom riders today to get a few bits and pieces will start putting the bike back together ...
Might get it done for MK in a couple of weeks !!
-
went to custom riders yesterday got to say what a great bunch of guys really helpful sorted me out with all the bits I needed and kept the cost in check ... even gave me a fork stem bearing cup for nothing out of the "odds and Sods" box ...
I could not help putting a few bits together ...
[attachment=1]
-
superb! they're a great shop and always happy to help
-
Now slap it together :slayer:
-
Just a quick update
front wheel completed looks good I was going to paint the rims but thought better of it I will use the bike so it will only rub off ...
[attachment=1]
Big problem I have is the back wheel axle "cone nuts" one of which is knackered I have no idea were to get one if anyone has a spare please let me know ... I will get all the plating back next week if I can get a bearing cone nut I can get the bike ready for MK ...
[attachment=2]
-
Can't help you with the cone nut.......But, you're doing a top notch job on what most would say is a bike that isn't worth it.
I love the unloved bikes from this era, I've got a 2000ish heavy bastard WTP Thrillseeker waiting in the wings for a resto, unlike you though, mine will be a very slow build.
Liking how this is coming along :daumenhoch:
-
I know what your saying I aim to do something a bit more old school after this one I just like the look of this bike and it's not costing much and a good starting point ..
-
It's a great starting point, and nice to see a bike from this era getting the amount of work you're putting in :daumenhoch:
-
I found a second hand axle went up the local bike shop they had a complete 14mm axle with cones, lock nuts and washers with new ball bearings £10 :slayer:
-
After a full on eve/night in the garage this is the results ... very please with the bike it has come out really nice and for me looks about right with the polished metal ...
Need to fit the front calliper when I get it this week and sort a seat out ...
The total cost including the purchase of the bike £159.00 my budget of £50.00 was about right when you use the "rule of restoration" which is estimate the build cost and triple it ... It is a heavy old beast but with new bearings it is a nice bike to ride it carries the weight well ...
I have enjoyed the whole process and thanks for the help along the way ...
Be good to know what you guys think ??
