sick of fixing that reverse motor so i decided to slap a b1 motor in with some extras.
ill keep posted on progress,
see what you all think

Surely the GP3 motor can't be worse than the B1 motors though?

Wow that fits better than I was thinking it would mate !

The clutch side looks much better for clearance than I imagined it would.

Keep the photo's coming man !

What are you doing with the left over reverse engine ?

Yep they are.

Nice work stallion.

**imdying** · 10th December 2010, 14:52

Daz mate you forgot the pullstarts bust real easy to !.

I'm on number 3 now....

I also found the stock seal's are crap... replaced all of them and the bearings....

what sort of problems mr "imdying" have you had with the B1 motor ??? I've had a water pump fail seals installed wrong from china.... that killed a top end... i know this is common.....

Other than that if you build them right they seem to problem free for me. My b1 racer has been real good.... other than the clutch....

nearly there, gona start up tomorow see how it runs, ended up with a modded b1 exhaust, modded water piping to suit gp3 radiator. fits in there nice and neatly, just need to do muffler and a foot peg then should be good to go lol.

i have been through 3 wrist pin bearings, piston, head, clutch (fell to bits), and the clutch is forever cumming loose and ended up wreaking the crank and those stupid plastic pull starts always break. but i do know of a few others that are having better luck
