Anybody Running 15 Tooth Front Sprocket

[MikeTheBoss]

Did anyone have a problem with running a 15 tooth front sprocket? I installed one today.

First off,

I had to cut some plastic out of my crankcase cover to allow it to be seated properly. The chain was interfering with the backside of the cover.

and

When i went on a test run and returned I saw that the chain literally ate up that rubber chain roller. It is no longer there, its just metal.

The 15 tooth sprocket is significantly larger than the stock which is why it ate up the chain roller.

To make things worse I may have over heated my Vitos BBK when I opened up full-throttle. My exhaust was sounding nothing like it normally does. Now tomorrow Im going to have to rip the top end open again and see whats going on.Im so pissed now Im just going to put the stock sprocket on and call it a day.

did u have to grind out of the case too?

yea use a 14t, mine is running great with it on.
i believe you have to grind the case to fit it on there aswell.

Yea you absolutely have to grind the case. Im just browsing the forum now and it is a regular occurance which is no way of getting around it. That wasnt a problem tho and was fairly easy, it just caught me by suprise as I was putting the cover back on.

I am about to rip Vito's Performance a new ahole if sh*t grenaded again. My Blaster just bogged down and died in a snow storm last winter and would not start back up and did not sound right. I finally got a chance to take apart the top end 2 weeks ago and my piston was fried and chunks of the piston grenaded. The cylinder was in pretty good condition believe it or not. I got it honed, slapped a new piston on and it was running like it always did.


FYI, I was 1 mile from my house when my Blaster died and was by myself. It was all uphill to my house too besides one little downhill about 25 yards long. I can honestly say that was the hardest work I have ever done. And trust me, Ive been doing labor jobs since I was 16.

that sucks man, when u rebuilt it, did u get the cast piston or forged??, the cast pistons are junk and will bust apart, get a forged if u have to rebuild it again

Nah man i got the cast piston. Im going away to college so Im trying to get it running at its peak so I can get the most money out of it. I had the 15t sprocket laying around my garage for over a year.
