So with the new plug how long should I run it to have it tell me all of that? I've basically been going up on jet size either waiting for it to become excessively rich and start stumbling at wot so I can then go down a jet or 2 to get the tune as close as possible without being to lean. Im also...

yes I am doing a proper plug chop killing ignition at wot

Here are the photos of about 10-15 min running back and forth at wot with a 142 main jet Let me know what you guys think should I keep adding more fuel?

sorry i have been away on vacation and have recently gotten back. @ Kentucky boy the way the fuel line has to run to attach to the mikuni carb it sits at about half way up the tank which once the fuel reaches that level it wont be able to gravity feed anymore. I haven't had any issues with the...

Thank you all for the help.

I also did plug readings all the way through the assortment of jets that I had with me. The largest being a 134. I still have to read the plug from that test pass but the 130 jet was reading lean from wot plug read so I put the 134 jet the largest I had with me in and it felt strong. I need to...

So this took me allot longer to figure out than I like to admit.:mad2: the reason my predator212 build wouldn't rev out past 4500 rpm was due to the air filter I had installed on the mikuni. After switching back to the deformed filter that came with the mikuni kit It finally revved out nice...

And the keyway on the predator engine was in the same location as the Coleman's flywheel

I have tried swapping coils I'll put the 130 back in it and see what happens I'm going to take it out to an empty parking lot for tuneing today. And do you mean keyway not jetway? I'm also thinking of putting the stock timeing key back In it and see if that helps.

i will double check my plug gap tomorrow i am almost debating to bite the bullet and order either a Tiliotson tct carb or a Tolliotson HL-334 wx carb kit from omb warehouse. BECAUSE I CANNOT FIGURE THIS THING OUT:censored::censored::mad2::mad2::mad2::2guns: A high/low speed adjustable jet v.s...

Here are the photos

Thought I would post some pictures of the machine I was able to get a few test rips in before the police arrived because of course people dont have anything better to do than complain. But it still breaks up around 5,000 rpm With the 8 degree timeing key and a 0.010"head gasket . Im going to...

That's choke off. It's got a mikuni vm22 on it and the enrichiner or choke raises the idle rpm to around 2 k. I'm about to go mess around with it now Want to do a few plug readings and will update a little later on tonight

So yesterday my new head gasket and 8 degree timeing key arrived got it all installed last night but was unable to take it for a ride because it got too late and I didn't want to upset the neighbors. I'll post an update along with some photos of the build tonight when I get off of work. I...

I started with a 130 main jet and a 12.5 pilot with a 12.5 pilot it was hard to start and a 130 main it was way to fat I've been re jetting threw this entire process. I have jet sized ranging from 100-140 for the mains like I said I've got my idle dialed in perfect. Has anyone ever seen or...

So I took it out again tonight a brisk 24 degrees it fired right up first pull, went for a wot RIP up and down the street and it still broke up on the top end got back did a plug reading and it showed lean so I raised the needle as far as I could raise it went for another RIP got back read it...

Unfortunately the customer didn't want a billit flywheel he doesn't plan on being at wot all the time and he understood the risk of the flywheel magnets coming apart. The valve springs are from nr racing that were advertised for working with the predator 212 hemi. Unfortunately arc doesn't make...
