i have a stock muffler thats been just sitting around since i got my fmf t4
i'd be willing to trade or do it for money what ever floats your boat lol
pm if your interrested
i use fully synthetic spectro gold and during the winter 10w 30
but during the summer i use 20w 50
so far i love the stuff it proves to work really well and keep the engine cooler
what about just trying thicker oil??
i run 20w 40 with an oil cooler
this may have already be mentioned or something of that type i might have missed while reading
lol
the throttle linkage is a pain but its easy to get off
but after you take it off dont move your cable
i ended up moving mine and i had to re route the cable and it was apain to get the exact same way again without having it rev up evey time i turn the bars or something of that type...
well when i was riding with a bunch of utility bikes they had a odometer and after the math it said around 33mpgs but thats with not riding hard at all just chillin in woods like 4th or 3rd
and i think we did around 100 miles that day and i didnt have to fill up once
and thats complety stock
mines done that since ive gotten it 3 years ago and still does
i havent had an issue with the clutch yet so id assume that your alright
idk how much that helps lol
