Need a new starting point

[eness76]

Guys, I have just finished a craigslist blaster find that was missing the whole top end among other things. It was stock. I had a right side bend pipe and silencer from a blaster I had long ago so I cleaned it up and out that on. I also ported a new eBay cylinder per Ken's YouTube raising the exhaust port 1 mm. It has new boyesen power reeds and a no toil filter with no lid. I started with a 280 main and chopped today and was clearly lean. Where do you guys suggest I start now, 300? Thanks.

Also premixing 32:1

start higher for a right bend...330-ish

 

[eness76]

Thanks Awk! That's what I'll do.

sorry to thread jack.....that machine looks clean as hell though~!

Thanks! It was a real mess, the guy I bought it from got it from a storage unit auction like on tv. I'm guessing the top end needed done and somebody tore it down and lost interest. The bike was a filthy mess and neglected. Bearings, bushings the whole deal. Once I get this jetting dialed I'm going to get some new wheels and tires. Those rears are huge!

What size are they?
I actually prefer larger, they roll in and over things easier and offer a bit more clearance. On a track, no big deal.

 

[eness76]

they're 22s, I'm going to keep these for trail use but I prefer to have 18s for the track.

If your gearing is good with the 22s, you'll have to gear up when you go with 18s
