Ok, I'm looking to the forum for some help here!! I recently tried to run a trx 2.5 in my losi. Ran into a few problems! I didn't notice this when I fired the motor in but the clutchbell rubs against the back of the slipper. I am looking to you guys to tell me wether or not I have to dremel the chassis to move the motor back or the rearend forward. Or if there is an easier way to do it? My other thought is just to get 2 scrap pieces of metal and drill and tap my own holes where I need them!

Thanks for the help in advance!

is there anyway u could put a shim on the spur gear to move it out more, that would save u alot of trouble

Tried that and the binding only gets worst!

Do you have a photo of it? Do you have shims behind the flywheel? Is the flywheel collet sticking out the back of the flywheel a little bit?

I had that problem on my buggy... or savage, can't remember which. I had to grind about 1.5mm off the back of the collet because it stuck out the back of the flywheel too far. The collet would hit the bearing on the engine and obviously stop, but it wouldn't allow me to move the flywheel closer to the engine. I think I was having the problem on my buggy. The flywheel was rubbing on my brake disks.

I'll try to put picture up later.
