Steve is building our Billy Bob Blue Wheelie-Smokin :lol: 2012 into a Real Street all motor bike. Fully realizing that it won't beat Ricky and the turbo boys. Spy photo enclosed. Mac 70" arm, Litz shock, Tsukigi big tube sidewinder ( If you went to the Orlando trade show this is the one that was on display). CZ wheels off my street bike. 3" slammerz, etc. etc, Damn it adds up. Stay tuned. LSL

Motor is a 1580 Lee. 2 mm bore and 3 mm stroke. Built for 5 mile WFO runs at Bonneville so somewhat conservative compared to a full on drag engine. Still made 247 HP with stock exhaust and non-oxy fuel. The chassis is so much more important in drag racing so that is our main focus. Also Marine said they won't make billet cranks for this engine as the cost would be prohibitive due to having to hob two gears onto the counterweights. We did manage to lengthen the rods .100 ( even with the added stroke) by going with a 2-ring piston and smaller diameter pin. Anyway it is all talk until the time card shows the results. Stay tuned. LSL

Gen 2 MTC which requires splitting the cases to install early ZX-14 mainshaft. Sucks, but at least it is Winter here. Yes, Rock makes one for the 14R but their customer service is so bad you can't even get them to answer emails or the phone to order one. More work for Steve but MTC makes nice stuff that works. LSL

That is what the guys are doing using the gen 1 shaft ... Sucks but it works .. Seems the guys don't want to retool and cut the basket a bit different to fit the Gen 2 shaft.. Soon there will be more Gen 2s racing than Gen 1s .. It's going to make the Gen 1 out put shafts hard to find ..At some point they are going to have to retool and make a Gen 2 basket and hub ..

You're really going to have to lighten that thing up for Real Street.... well, as much as you can per the rules.

So you made 247 with stock exhausts!?! If you can get close to 275, REALLY take some weight off, and nail the chassis setup you probably won't be too far off... Unfortunately anything less than that and you just won't be in the ball game.

I hope you guys nail it though and it will be cool to see a different combination out there. I was completely surprised that none of the big name builders/teams took advantage of the all motor rules last year. A 300hp all motor busa will do some damage when setup right, at least that's my opinion.

Good luck and keep us updated!

Also, NHDRO has a new class for 2015 that you all could easily run with this setup. It should be a lot of fun! Almost a cross between Real Street and Grudge.

"True Street" is and 1/8th mile class with an "instant green" start. Only 3 rules; Street Tire, No Cut Frame Rails, and OEM Hand Clutch.

So you all would only have to put a stock clutch back in and get it! I can only imagine your setup would be VERY good at 1/8th mile and you would only have to make that one small change.

All 100% correct unfortunately as I found out, however MTC did tell me they are working on a clutch for the 2012 up bikes and hope to have it ready around April 2015

Well it finally made it to the track last week. Sometimes life just gets in the way. Steve had a friend ride so he could watch the launch and make adjustments to the MTC Gen2. Made three runs, best ET was 8.22 and MPH 170. Pretty good start but I don't think JT has to worry :mrgreen: LSL

BTW you guys Removing the air filter? This still has it in, I guess you have to cut it out to plug the slot in the frame.

Steve: The bikes' seem to run the best with the screen removed but the filter element in place. Steve forgot to mention that he ran the bike himself this week and had a best speed of 173. No ET improvement as the bike was pulling off the groove probably due to the tire which is an old Power One off my street bike. Time for a Hook-Up. Hope to race it at Atco this weekend if the weather holds. Stay tuned. LSL
