Dual carb manifold for Big Red, she's got some massive ports.
How did you get her to 702cc? I'm assuming a 676 kit with a stroked crank?
What cc and valve size?
Update on frames;
We've been getting a lot of emails/calls about updates. Things are still moving along, slowly but surly. As for pricing, we're looking around $4500 for a frame kit (frame, swingarm & pivot, linkage, and miscellaneous hardware).
We are not accepting any orders yet. If you are serious about purchasing a frame and would like to be informed when we start taking orders please email info@rotax.us or text (951) 213-4414.
This is not a waiting/pre-order list, frames will be first come first served. When the time comes, you will be notified via email, your spot is determined when we receive a deposit.
We were informed today how much someone in the ATK parts business is selling replacement rings for stock 97mm pistons.
Roughly $125 for a set of Total Seal brand rings! I mean, stock Rotax rings were not cheap, as is the case with many Rotax parts but $125 is outright ridiculous!
Now, We're all for making a buck. But we sell Total Seal brand replacement rings for $40/set, even our performance pistons rings are only $55! Many parts we stock for the Rotax motors are sourced from somewhere other than Rotax, some cheaper that stock, some not. We're not going to charge stock prices when we get it for less than a quarter the price. If we save a buck, you save a buck.
For a reference, a stock OEM Rotax ring set would run about $160
Price gouging is the same as toilet paper hoarding for resale.
Thanks for looking out for the little guy! 😊
Elliott its a great thing that you are keeping Rotaxes going !!! Keep it up buddy !!!
👍👍
Should be good for another valve job, right?
Ah less hrp = less wheel spin. Saves tires so going green!
Where I come from we call that junk.
One of those fancy multi angle valves 😂
One for the scrap box...
Ture to form !
Getting started on @ian_45e 676. Sporting a new set of cases and bearings.
Very Nice, and Thank you.
Attempt two at the 1992 ATK 604 engine. The hardest thing about this one was giving up my early electric start clutch/belt cover I was saving for a future street tracker build (thanks UPS). At least we got everything re coated, a bit shiny but still a beauty. The @metrolakes engine stand has done me well the last few months, handles the 100lb+ engines with ease. Next up, 504, 604, and 676 flat track motors.
Could save the cover. Weld it up.
Those engines are huge!
What was the average and the max horsepower produced by these motors
Sometimes clean is not clean enough, you just have to go the extra step and vapor blast. Spotless.
Dry blasting vs wet blasting, what finish do you prefer? Kawasaki G31M head.
Smooth and it's a Green Streak 💪👊✊
I would prefer dry if I was painting it
Don't really care how pretty it is . When I drop the hammer I want that S.O.B. to feel like a rocket !
Dry! Looks more original.
Right looks better
The one on the right
Either !
Wet. 👍
