That's awesome man! You must be at a lower elevation to end up with a 350 main. - Jared

I have had a couple packages go completely missing using USPS. My guess is the lazy ass postal service people are delivering the packages to the wrong places and whoever gets them tosses it in the trash or just keeps it for themselves. - Jared

Get a fiberglass fender and get it painted. Don't waste your time on painting plastic. - Jared

I don't think he wants to part it out right now. Trying to sell as a whole. - Jared

LOL I believe this engine ran good back when it only had jim's porting on it (it didn't belong to me back then) and when that owner sold it to someone else, the 2nd owner ONLY deal with Tim @ Titan. He had tim go through it and port it to his specs and had tim cut some domes specific to the porting it had. I honestly couldn't tell you if Tim went through and completely re-did everything, or if he just touched it up and did the assembly. I will say that the cylidners do have some distinct characteristics of jim's porting (HUGE exhaust area). It is definitely one of the hardest running engines I have ever personally owned. I think the only thing that might have ran better than this setup was the 612cc twister I got from Firehead. This cub is almost too much engine for what we have to ride on around here, but I enjoy it. - Jared

Got any friends with CPI pipes you could borrow for a day and try out? If you have friends with either pipe borrow them and give each one a try... I have CPI, small bore shearer, and big-bore shearer that I swap around from time to time. I like each pipe for different stuff. - Jared

Get some cascade CSFX silencers.

A colder burn will actually reduce power. The more heat created in the explosion the more power it will make. Methanol actually burns much much hotter than gas, but has a lower heat latency, so it is much cooler going into the engine, but once it is ignited and burns the flame front is much hotter than gas producing more power. It will gain you nothing at all to run any race-gas mix unless you need it. (i.e. higher compression, higher timing, etc) It is basically the same stuff as pump gas with a higher octane rating. There's no hidden power in the fuel, it just resists detonation better. The engine setup that requires you to run the race gas is where the power difference is coming from, not the fuel. - Jared

Timing Plate set @ +4 deg. Pod Filters on the carbs if they don't already have them. Dual Stage Reeds on your stock cages shift-star mod if you want to stick with pump-gas then keep the stock head for now. down the road you can swap over to a cool head. The above are cheap and easy mods that probably wouldn't break your budget. - Jared

Its a float guide. You don't want to run without it or your floats can turn and get stuck at there in the top. Call up sudco & tell them you need a Needle Valve Keeper plate for whatever size mikuni's you have & they should have it. - Jared

I would do a Mikuni 32 TM Flatslide or a Keihin 33 PWK. Both would be good carbs for ya. - Jared

Yeah, kevin does some awesome work. Right now I have a 10mil cub that Tim @ Titan redid after Jim @ Passion ported it. Its amazing how much different the power is from a stock cub. Check out some of the frames stellar is turning out now, he has some awesome stuff. Brandon @ wildcard is running a hybrid single a-arm frame that looks awesome. - Jared

This is interesting reading all this track info. I wish we had a track close to us, it would be fun to give it a try. daj, are you getting back into the banshee stuff?

Just cut some of the length off your spings you have now... Been doing it like that for years and years. Works fine & its free.

If the skirts broke off it was probably excessive piston to cylinder-wall clearance or you had some detonation issues and the pistons couldn't handle it and broke.

Matt is correct, these particular sleeves can go to 76mm. There is a TON of life left in them. This is a great deal for an awesome dune motor. This thing runs awesome.

$3200 for complete engine. + Shipping 4mil 466cc Small-Block Twister Bead-Blasted matching halves stock cases bored and port-matched to the twister cylinders 4mil hotrods crank trued and welded max-load bearings on both ends of crank 71.5mm bore Small-Block Twister Cylinders Aggressive dune port from Kevin @ HJR Wiseco 423 series pistons with about 15hrs on them 25cc domes (175lbs compression at sea level, and 130lbs compression at 7200ft elevation) Vforce3 Reeds Billet Intakes 33-35mm Adjustable timing plate lightened flywheel straight-cut gears magnum billet basket direct drive lockup & cover billet impeller billet water pump cover pancake bearing shift-star mod side-cut gears shift-shaft mod billet stator cover This engine will make right around the 100hp mark on methanol. I am selling this for my buddy Overdose. It runs good, no problems. He wants to build a 10mil. I built this engine back in october. Everything on it is nicely polished now. Feel free to PM me with any questions. $400 for the carbs + shipping Keihin 33 PWK's set up for methanol by me. Chariot Billet Bowls (the big ones) .118 dumps & mains EGL Needles Clippard Power-Jets with K&T cut powerjet needles 68 pilots Uni POD Filters & outerwears gravity-feed

Bottom End Traded to hp2000! Thanks man! - Jared

It may be gone on a trade. I'll know by the end of the week. If you have a set of stock cases send them to me and I will bead-blast and heat-wash them for you free and ship them back to ya. They would look just like these ones do. - Jared

What are the mains and dumps drilled to? what size pilots? What needles? One float or two in the bowls? Stock needles or modified needles in the clippard powerjets?

The 1986 models are the best if you can find them...

I would do it again and see if you get the same reading twice. To me that looks like a non-existant ring, which would indicate a lean condition. What is your jetting mods and elevation? Also, why are you running 9's?

What about the valve stem bearing?
