17000 rpm on the rev limiter!

I can’t watch another video of you bangin the revy halfway down the straight. I’ll leave!

im not used to the limiter on a rotax but it does sound pretty cool i wont lie

I'd love to ride on that track.

"Hands heal, gloves don't". Haha. Your dad is a smart man. You never know how high you can go until she blow!!

If he won't raise the limiter maybe talk him into supplying a 450 framer. 😉👊✊

Let that thing eat Mike we crank are rotax snowmobile engines to 9800 you should be able to do it lol. Good luck this year guys!!

Fun until I saw the make america great hat🤮

You can definitely rev it to 10k safely just requires Flat Track Factory to do some more r&d. I’m thinking plain bearing oil feed crank reinforced cases pankl rod and a custom designed slipper piston under milled for weight reduction. And if your gonna go that far your obviously gonna need to fit a larger clutch assembly to handle power increase which will require custom milled cases. And the transmission gear fatigue also becomes a factor but that can also be fixed by any good edm machine shop for a fair price I’m sure. Also I almost forgot probably going to need to add oil squirters probably one more for under piston to control added heat also going to have to make sure engine doesn’t wet sump. So a deep sump would be required also an oil cooler would probably be necessary. This is all that needs to be done.

lol...easy for Sammy to say...TWIST IT!!! "You provide the engines"....a couple more beers and I bet it would run WAY better with it revving @11,000...Yeah baby!!!

10,600

Agree on 9700😂😂😂😂😂😂😂😂😂😂😂

Massage the front brake on the right handers. if you could have raced an Ascot tt you would have been forced to learn it or you woulda had your ass handed to ya. also gear the limiter out of the equation. or like you said let her eat/ breath. old school says the limiter is in your right hand.

Small block Chevys rev 10k at the drag strip no problem. I think the Rotax could handle a couple seconds! Same size pistons.

I have 1989 ron wood rotax engine In a champion frame

Gotta finish to win. I'd trust Mike and let him set the limit. If you hit the limit so soon, can't you adjust gearing a little?

...scream it, or ride it off the bottom... that is the question

Ti valves + ti retainers & ti Rod & lighten the piston with the correct length stepped header & intake track . everything being equal More rpm = more HP but You also need the correct valve springs or it will float the valves then the valves have sex with the piston which you don’t want.

9850

I think you should look at the Dyno. Potentially change gearing to the track.

How about 400 more rpm

Rev it higher. It’s a race bike

“ I’m too pretty to get dirty” 😂 Love the shop talk! Great video!

Let the Rotax sing… Elliott probably still has cases.. Nort👍

I think you just gotta take a couple teeth off the rear

Gear it longer lol. In my limited engine knowledge, I personally don’t think being on the limiter is good for an engine. Still dumping fuel through, but not firing the plug. So And yeah, it sounds dumb too lol. Just reached the end of the video, yes take it to the dyno, see where power falls off! Dyno video!!!

Let it Rev! This stuff is Gold!!

Old rev limiter was floating the valves

I think Mike is kind of a cry baby.

That motor has to be 5 grand not counting the head. I would be careful.

My rotax was a 500 so i dont really know ho hi a 680 would rev. When i was a jr we were allowed 500 singles or 750 twins with restrictors.But never really woryed about revs.

Always nice to see you guys just chilling in the garage in such a relaxed ambient... only talking bikes and trash talking... as you do! ahahahah. As for the rev limiter... Show us the line and the RPM´s when you dyno it (no need to show the power figures to the competition!)

I do agree the limiter needs to be bumped up a bit, but I have no clue how much this engine costs. Any estimate on the cost of Michael's Rotax?

Revvv it up!!!

100% agree on 40psi on a fresh mounted tire till your ready to go. IMO it helps set bead and stretch tire. Settle at 9500 rpm’s Sammy! Fans have spoken.

I say the limiter needs to be upped a little bit!

Nice vid Guys !

Yup let it eat 🚴🏁

If Harley made a street legal version of this bike and could keep it under 10k they could actually sell some bikes. Retro style scramblers/flat trackers are popular right now.

Ya NUT 😂🤣🤪😜🦾🏁-- BETTER 2 do that on your play track than at Val's ranch 😂🙌🤘

I got a signature of You

that track looks fun

Holy shit! Is he okay?

ouch'

Totally

Great video, great racing! Thanks

That bike pulls hard man 👍👍

Very good video Sammy sorry you went down hard. You rode the first heat expertly. That rider hit the brakes early i thought. Hope you are ok that was a hard hit. Very cool watching you smoke the field on the Rotax. I am sure you would have won the main. But I am glad you didn’t and risk your health. Man that bike runs and handles good. 👍💪🏽🤟🏽👏👏👏👏
