Hey fellas, its been a while since I've been on the site, but I figured now is as good a time as any to bring this up. (Please move the topic if it doesn't fit this board). as the title states, I have come to the realization, that I want to compete at the highest level of vintage racing and to do so, I am going to build a IFS replica shark over the next 2 years. i am in the beginning stages, starting with research, I have also reached out to Kawasaki Development for any details they could possibly give me, they got back to me this morning with little to no info, but still cool that I received a response. I have decided to develop my own hood due to seeing little imperfections within others designs and I will be modeling the entire snowmobile in CAD within the next couple months. My request is this I need pictures, I have basically all the ones I can find on the internet but i need some more if they exist. i am taking measurements off of the pictures and using that to piece together this machine. i have an appointment setup with a gentleman i know, for Friday, to measure a 1975 sno-jet thunder jet tunnel (was supposedly used to create the sharks back in the day). basically any details that you guys might have, i would be so so grateful for. I will Keep Yall updated as i go, i am super excited for this challenge!

Looks like a fun adventure,  our trails have been open for just over a week now.

I’m running p85s on my Invaders, they work extremely well.  Not sure on the fitment on a Drifter, do they use the 30mm taper?  I know that you need to be careful which p85 you use on the Invaders because of the back spacing, some p85s will hit the engine mount….  You would also need to run a Polaris secondary to match the p85. 

Good luck! 

do not use ufos lol. these motors do not like to work with 3.5 sliders imo.

I have never had this problem.  The last couple years it's been due to no snow.
