My MK1 never brakes down ? Even before a motor re build the gear cogs were on the wrong way but it still went less one gear. Motor re build all bearings came out and back in no worrys even the modified one's to fit the MK2 gears that do all work! Dam and what do i do about this problem when i take o...

And I will add my motor all top end is MK2 the gears are MK2 carb is MK3 air box is MK1 but with a lot more holes for air Twin Air filter MK3 reed rubber that that's been ground out to let a lot more intake from the carb as well as casing on other side of reed block have been ported as well and Boye...

I am on my second back sub frame as the one on the bike was rusted out and nearly number 3 as I bent the crap out off it but managed to get it strait again as for yours no problem paint it. If you want to go back to use'ing a oil pump if it is missing from your bike that maybe a bit ore tricky to ge...

Here's a photo or two of the pipes sorry don't have any better photos and my motor is still in bits waiting for parts.

On my mk1 the forks that came on it are 1991 CR125 forks but I have seen a old photo of my bike with another set on it as well I have no idea what they were. But I know I can fit Cr250 as well as Kx250 forks in to the triple clamps. I believe Kackered said to fit other forks on to a mk1 you had to s...

You well are probably right knackered would I have to get a new front sprocket ? it sort of looks like the big washer that holds the front sprocket on a mk1 fits in to it some how for that mater can you even still get them ?
Its just I am trying to keep costs down I have retired now .

How stupid am I I already have a mk2 back gear shaft in or out at this point so it do's fit so now I am confused? So thanks Hallsy I might get my mate to ship over my other back shaft from the mk2 and see how things fit together first before buying yet more parts. thank you very much for the offer a...

I have a mk1 engine that I have stripped for parts, gearbox looks to be in good condition, but shipping to Thailand would likely be too expensive to make it worthwhile? Yes that would be wonderful thanks Hallsy The back drive shaft with all it's gear please. What ever price you feel is right and th...

Okay just re reading what you have said I do not think the shaft gears will fit and there's no way to get the work done here to make them work so it looks like I will have to buy another mk1 motor for parts or just part my bike out and buy another bike and its not easy buying a good bike here in Tha...

Thanks for that Knackerded Let me put it this way if I was to leave the clutch shaft as it is and just put in the mk2 back drive shaft gears and all would it fit ?
And as the crank up and down its hard to tell if any but it sort of sounds like the baring might be on its way out.

Sorry what do you mean by up and down ? from what I could work out from FAQ its the front gear shaft to the clutch that is smaller the back drive shaft ?

As I had a knock in my mk1 motor and with a broken wrist which is mending I have pulled my motor apart and have found out why I had no 6th gear it has spun on the shaft and worn it down so my back gear drive shaft is F....d I have the gear box for a mk2 back in Australia and am getting a mate to sen...

This is a photo of the pick ups on a CRM MK1 I am re building my motor at the moment.

off the top bolt of your fork triple clamps

I am not sure about the MK3 but I got a set of LED front indicators a while back but after reading what knackered said on his rebuild of his MK1 you need to wire in a capacitor for them to work. I did fit 2 LED flat slim line ones to the back mudguard with the standard front ones they work no proble...
