exaust port barely opening@TDC

So I have a treat's parma kit on my 50v av7. the bike runs great! But the exhaust port opens ever so slightly at tdc. I know I will be loosing some charge but will this cause a seizure or something bad?

Re: exaust port barely opening@TDC

The bottom of the piston skirt is uncovering the exhaust at tdc?

Bump

Re: exaust port barely opening@TDC

Gardude - we had been talking about this last year and such - do a search with my name and/or av7 parma, etc. Some people double up on base gaskets (me) others made plates, whathaveyou.

Re: exaust port barely opening@TDC

yea I know mick. it runs great! not worried about it unless it is going to cause some sort of damage.

Re: exaust port barely opening@TDC

it will be fine.

Re: exaust port barely opening@TDC

Word!

Re: exaust port barely opening@TDC

Oh yeah you are one of the original Parma guys posting Jesse, I recognize now. Well, wait you are just getting it running now? I know several that just ran it with the port opening like that and I think it was fine.

Re: exaust port barely opening@TDC

no I had it running really well. then me and my bro went for a very long ride! ended up melting a hole in my piston. Kit was fine. I have just recently been able to buy a new piston and get it running again. :). Checked the timing and it was fine. still set a stock position. Just don't want to blow this one up again.

Re: exaust port barely opening@TDC

I think it is .093 off the top of the cylinder with two base gaskets.

Re: exaust port barely opening@TDC

the only damage will be to your top speed and performance. you will definatly lose alot of charge

Re: exaust port barely opening@TDC

well it is going way over 50. :)

Re: exaust port barely opening@TDC

Was the hole melted like wax or flaky like sandy pastry?

Re: exaust port barely opening@TDC

it was from too much timing if i remember from the pics. or the squish set too high

Re: exaust port barely opening@TDC

Paul it was flaky! I checked the timing and it seemed fine. I have a base gasket that is now like .5mm thicker than when it blew I think I need to add another one.
