Hi I just bought a Honda 250r trike and I am having trouble with the fuel mix, the sticker on the tank says 20:1 petrol (gas) to oil but it wont run right for me? The bike has had a complete engine rebuild with new gaskets and seals. The barrell has been bored out to suit a new larger .75mm wiseco piston. It has new EBC friction plates and clutch springs with a new clutch cable. The work on the bike had been carried out by the last owner so would this make a difference to the mix? I read somewhere that people were using 32:1 mix, is there any rule on this or is it a case of trial and error? Any help would be appreciated. Alvin

 

i run 32/1 heard of guys runnin 40/1 i have a 84&85 250r when i got my first one the 84 the kid i got it from was runnin the 20/1, the 2 stroke oils are a much better quality now than they were in 82, mine ran like crap w 20/1, pipes were full of oil ,it was blowin it out the end.

 

Thanks for the reply 4bratsdad, I will try the 32:1 mix and see how I get on, but I now have another issue, the gear selector is moving on the shaft and not selecting gear, the grip treads are worn too much so I must get a new one, someone did suggest welding it too the shaft, but I would prefer to get the right one for it. Where do you guys get your parts? Alvin.

 

go to ebay type in honda 250r atc make sure it says for your years, pretty sure the 85-86 wont work, not real sure if the 81-82 first generation 250r will work with 83-84 2nd gen 250r, check out air foolers .com whole site dedicated to air cooled 3 wheelers

 

I managed to find my way over there to that site 4bratsdad, Thank you, lots of useful hints and tip's for someone like me!

 

glad i could help, just bought my first atc250r few months back,2nd 1 last week its an addiction, lookin to buy a parts lot from couple guys, maybe i could sell some get my money back, anything you need let me know, this guy ive been dealin with has some 81-82 stuff ,all air cooled250r, i saw a chrome heat guard on a stock 81-82 head pipe, lots of engine parts let me know

 

i just bought a 83 250r for 750$ and i run 50:1 and its perfect, its a little rich but thats what you want.

 

Does anyone know how much oil i should put in my 1983 250r, please respond!!!

 

'83-250r do you need to know how much trans oil you need ? there's a plug in the left side case marked "fluid level" i believe...take that out and with the trike on level ground fill it till it weeps out the hole and your full

 

yea i figured that out shortly after i posted that but thanks anyway
