I gave the bike a bit of a service and the air filter was cleaned, it was not particularly dirty though. I am not sure about the jets, the carb is stock but the bike has a dynojet sticker on it somewhere so it might have been fiddled with at some point. The bike does backfire a bit under decelleration which could suggest that it might need a bit of a tweak and the baffle has been removed from the stock silencer too. I didn't like it so loud so made up an end pipe which made it much quieter. i would prefer the baffle in but I don't have it.... anybody got one going spare??
Everyone says change the pipe but they cost loads and the one on it is good so it can stay for now.

Stok pipes are fine for what they are. No reason to change, theres no big powercurve to gain from it. The stock exhasut is heavy, but so is stainlees steel ones.

If you put in a homemade baffle, and are running a dynojet kit, you coooould be running a tad rich, giving you more fuel consumption.

Any tips for better economy?

I get very similar from my 1986 1VJ (standard except for Laserpro end can). Commuting in UK gives about 400km before reserve, and I can usually get about 21 litres in then. That's a mix of A, B and motorway with a max cruising speed of about 110km/h.. The tank is pretty dented so I'm close to the theoretical 23 litre max at this capacity. The economy suffers a bit on the piste tho...lower gears, more revs and luggage...

My 88 xt600, stock w/ Acerbis tank gets 38 miles/gallon.

My 89 xt600 w/ Cobra exhaust gets about 42 miles/gallon, and I don't baby either of them.

Trade it in for a lean burn Enfield.. Over the last year I have averaged 96mpg with mine. Usually in the 50-65mph range cruising. ATM I have a 14 litre tank and I have yet to put more than 12 litres in it which gives me 240 mile range. I do have a new 22 litre tank for it, but it is the wrong colour so have not yet fitted it. That should give me an easy 400 mile range.
