Thats what I thought Pooh. Ordered a pair tonight. Less than $8 for the pair. Hopefully they wont be junk. If they dont work out I will look at getting a good used pair locally. At least they make adapters to fit things.

Fixed my clutch cable issue. I purchased a used Honda CBR clutch assembly, had to work it a little. Not really happy with it.. but it works for now. I actually had to combine the parts from the CBR with the stock Df parts to make it work. But it is good now. I am gonna buy a new set of handles for both sides soon to make it look a bit more uniform,,instead of one aluminum and one black. anyway. all is good,and back riding again. Put on another 150 miles today.. up to almost 4000 miles on her.

The DF carb mod explained:

I took pictures of when I inserted the washer on the needle - might make it easier for anyone else wanting to do this. I found the bike is running a lot smoother and not as lean with this mod:

First step is to cut off the fuel valve, remove the fuel line and air filter and then remove the carb. Next open up the bowl with the 3 copper screws - good idea to have a small container underneath it as you do this to ensure you don't spill the gas in the bowl on your motor. Check the size of your main jet - mine is 105 - I suggest replacing anything smaller than this for this bike (... unless you like all the popping and don't mind a hot motor...)

Open up the slider at the top and carefully take it out. compress the spring and release the inner cable through the groove and hole on the side. You should have the slider and the needle in your hand seperate from the carb now. Remove the holding pin inside the slider carefully with long nose pliers and extract the needle. The needle is seated in a small recess. insert 1 (or even 2 depending on how lean your mixture is) #4 washers (see picture) over the needle. The #4 washer should fit neatly under the base of the needle.

Put it all back again in the reverse order - make sure you insert the slider back correctly - look inside the sleeve - you will see a small "knob" that needs to be aligned with the groove on the side of the slider. Test your throttle function before starting the bike

you will feel the difference.... - a much smoother ride

That's exactly what I did with my carb, when I first removed the needle I freaked out because there where not adjustment slot... But lucky I have seemly infinite supply of washers. Good write up! It saves money from buying a carb kit. Now I just need to find me a slow jet!

Thanks alleykat - I now remember reading this some time ago - where did you end up with the jets - still have the 108 and 45 in? did you end up swapping out the 45 with a 42?
