Yeah Ive been running 91 octane mixed 50-1 with I think its walmart penzoil in both my 1990 6m6 bored 701, and my 2010 62t 701. I have a b limited pipe, jetting, and flow control on the 701 62t engine.

Im pretty sure the issue was 190 compression with 87 octane lol

When you go up in elevation the air gets thinner and the engine will naturally run richer, which would require a lower jet. When going down in elevation the air gets thicker (more concentrated) and the mixture will run leaner, requiring a higher jet. Check the manual, I think you should be...

Jetmaniac would probably know if you start a convo with them

It recently melted its #2 piston on its second trip after I got it, so if I'm going to be doing work I want to make sure its setup right to last awhile. Compression on #1 read about 185psi which surprised me, I would expect more around 165-175. The engine was a 650 converted to a 701 top end...

Piston #2 was melted. The #1 dome has a few nicks, the #2 dome has about double the nicks but nothing major. The case sleeve had a bit of slag stuck to the very top wall where piston had melted, I knocked it off with a light tap on a screwdriver and then scraped with a razer blade. Now I am...

I have worked on Honda/Subaru/Toyota auto engines and Honda street bike/dirtbike engines. Never a two stroke before though or a PWC engine. Ill pull the head and get some pics.

Went out and got a craftsman compression meter, cylinder 1 (closest to the bow) read 188 psi, cylinder 2 couldn't pull a psi reading at all.

By knocking I mean an abnormal engine metallicy noise, I cant be specific just that it doesnt sound like it should. Its rough to get started and will die if the throttle isn't being played with. When I started it at the shore and gave it gas it would hardly move and was very rough, died soon as...

$1k-$2k in California

Took my two new to me super jets out to the lake with my brother for the third time. All went well the last two times, but this time we made it maybe 3 minutes from the launch and I noticed my brother signaling to me and heading to shore. As I pulled up he said that he was riding along at about...

Wow, 4 and a half pages of BS. Awesome. I figured a thread titled Ported Cases might have actual info on doing just that... All the case porters shouldnt mind if images of their work gets out, professional quality work is what will attract buyers. Those that intend to port their cases...

Yeah but you got to use your ingenuity and create something yourself! :) Also I noticed I said limit line but meant hood strap setup. I have both. The ratchet is for the hood strap and is nice and centered. Ill try and get a pic up for you guys tomorrow, the double loop strap is the same thing...

Do you all prefer neoprene or nylon? Ive always thought that the neoprene was much easier against my skin and didnt notice any cons. Im about to buy two PDF's and am pretty set on the JetPilot Apex Side Entry Neoprene model.

People would probably pay up to 19.99 for such a thing. Id say keep it to $12.99-$15.99 or so to be profitable for your time and still attract lots of interest. I have a limit line setup and so I take a double loop strap over each bar end and then put the center underneath the latch for the...
