Re: Source and part #?

Post by MoonStomper » 12:42 pm Nov 16 2020

I noticed some wear on my slide when I recently installed a fresh kit. Mine runs pretty good, but always a little grumbly/less sharp off idle.
This sounds like worth a try... Where is the best place ya'll have found to source this slide? Part number?

Sudco carburetor akways has all the carb parts you will ever need. I found mine on ebay there about 60 bucks. Please read the entire post here as the needle position is very different i have the sea level figured out for you should be good to 4000 feet or so the carburetor will be completely reprogramed
You will be grinning ear to ear. Smile

QUESTIONS:
My H9 is still running the OEM pipe & OEM #5 slide (snorkle removed)...
Will this new #7 slide make the same improvements if still running the OEM pipe?

Yes this cleans up all the jetting issues at the low end we all suffered from this in not just a high performance mod it will make any bike run alot better and now i can see it will pay for it self in gasoline savings a win win Any 2 stroke i ever buy that has a 5 in it will be changed before i even ride it i consider it a must have in my book.
To any one trying this at higher elevations remember if your bike bogs off idle in low end you need to raise the needle until it goes away the old ways of tuning doesnt apply anymore
