how many miles will the average tuber engine clock up before it needs a rebuild and what usually wears out first  just been thinking that they are getting to be old bikes now but theres still plenty being used so the engines must be good for a fair bit. on my s3t i had the engine stripped and checked at 30000miles and all was good apart from cracked heads  my current m2 has over 50000 miles on it and runs great.

Muffin has done about 60000 miles now and apart from a slight hicup from a broken valve spring about 30000 miles ago is running great  Still all original barrels pistons heads valves crank clutch gearbox etc Oh and steering head bearings

I put 110,000 on a Sporty I used to race for 2 seasons and 130,000 on a Dyna I still have, plus 20k to 50k on various Buells over the past 2 decades. These lumps are probably among the most reliable engines out there if you leave them alone or even do minor mods. I rank their durability up there with a few Japanese I-4s from the early 80s like the KZ1000 and CB1000 which have seen well over 200k on some sites. You'll replace an oil pump drive gear, tappets and likely need a cylinder clean-up and an oversized piston during it's long life if you take care with routine maintenence. |

Make sure you change the oil n filter at regular intervals an 100,000 is no broblems.

Avoid long periods of either very low- or relatively high revving (don't try keeping up with Fireblades on the motorway - or anything else that has 60 bhp or more ) and the lovely engine should serve you well. I never stuck with complicated warming up procedures (fire up and go), and in its first 50k I never bothered with shorter oil-change intervals either (just standard 5k). Maybe one thing to keep an eye on is the infamous oil-pump drive plenty of posts on the Technical Forum. My M2's is still original at 70k but some fail a lot earlier. |

i`ve got a set of new isolaters ready to fit. i was going to do them when i changed the belt but they didn`t arrive in time so i`ll do them later. my daily ride to work and back (50 miles a day) involves a mix of suburban roads and the freeway so it allways gets fully warmed up and used well plus i like to let it rev out every once in a while  i`m going to drop the oil pump next service and have a look at the gears |
