Realistically, you are going to have to get numbers for your own setup and riding style over time. The above are only rough guidelines. With a larger main jet you may see significantly less than what we have experienced.Thanks for the input my bike is a 19 with dg pipe and larger main jet and i run 20psi on my tires and i mostly ride 50/50 pavement/ gravel road
There was no real reason to re-jet to make it run richer. A simple twist of the air/fuel mixture "Pilot Screw" could have done that. Being "Richer" leaves a lot of the fuel unburnt and fouls up the plug, top of the piston and the exhaust system. You might be able to still adjust it for the proper lean/rich mix with the pilot screw. What you want is your spark plug to have a nice but slightly burnt toast color on the porcelain. Your bike will run smoother, use less fuel and may require the "Choke" Enrichment lever to be utilized on cold start up. IMO all this re-jetting crap is just that unless you travel real high above sea level or do the ridiculous FMF muffler swap.Hello all, I have a noob question. I bought a 2014 TW... the seller mentioned that he had the carb jetted to run richer. The upshot is that I never have to use the choke, even in like the upper 30s (I'm at sea level in the Pacific NW). However, I'm getting like 55-60 miles until reserve (I've never worked out how much more to empty). I'm wondering: would re-jetting make that much of a difference on mileage?
OK...I have to ask...what is your beef with the FMF exhaust swap?IMO all this re-jetting crap is just that unless you travel real high above sea level or do the ridiculous FMF muffler swap.
"OK...I have to ask...what is your beef with the FMF exhaust swap?". I am really glad you asked but I think you answered your own question, you took it off and have no desire to put it back on. The FMF exhaust is an aftermarket system that sounds and looks cool to some, costs unnecessary $$ and does not give any TW much more in the line of performance. Yes, you can spend more $$ and mess with the carb to dial it in and even then you basically still get squat from all that time, effort and expense. The FMF exhaust is also unapproved in lots of State Forest Preserves such as NH. There really is nothing wrong with the stock exhaust system on the TW unless the stock exhaust is rusted, modified or beat to hell. Looking cool and sounding cool for no real gain and lots of added expense is a fools game IMO but for those who need to look and sound cool I say go for it. When ever I went to buy a TW that had an FMF system on it the first question I asked the seller was do you still have the original muffler that will go with the bike. Keep in mind TW in BC, I am strictly old school and if you want to really be Cool in my eyes just buy an XT225 Stainless Steel header pipe for your TW which does nothing but change the cool look a little.OK...I have to ask...what is your beef with the FMF exhaust swap?
When I bought this latest TW, it came with an FMF Powercore, but I longed for the stock sound of my old TW sewing machine, so I took the FMF off and put the OEM back on...
Don't know if I'll ever want the FMF back on....
That is a completely normal course of events, we all tend to want to make it something it is not or at least dial it in to our own liking. Those of us who know these bikes already understand there is very little you can do to milk the last ounce of power out of them. Farkles is the name of the game and maybe some sprocket gearing that better suits your needs.GaryL you make a lot of sense. From what I have seen tho, people dont like stock. If you get a 200, you try to make it a 250. If you get a 250, you try to make it a 450 and so on.
