Ok so I am new to this kind of thing but I need help
To start with got. 300ex 95 model
Pretty cheap was really he's to start and counter shaft was stripped so someone welded the front sprokit on
So after a couple of rides it broke so I desired to fix tore whole motor down and rebuilt top end when I got top end back together the cam marks were 1/2 tooth off I couldn't get the marks to line up perfict so I figured close enough so get it together and started right up but want. Take but half throttle then spits and sputters and backfires also start button wouldn't work
So I took my 400 ex carb and put on it and did the same thing so got a amr rev box and new monster coil same problem
Ready to sell it lol
Anyone can help be muchly appreciated
