Finally got around to watching this. Great explanations and I agree there are a lot of misconceptions on this topic. I have a number of ride buddies around or over 10:38 200# with stock springs on Austrian bikes, content with mediocre, harsh suspension performance from too much preload to get sag and no balance. Whaaaat?! Is ignorance bliss?😮 Well, it is cheaper until you get tossed on your head.
The Allballs/Moose/Pivot Works etc are cheap and they usually work well enough as long as you grease them regularly. If you want a higher quality I really like the Factory links kits.
How do you choose a fork spring rate? For instance the stock spring rate for a 17-19 KTM 300XC-W is a 4.2N/mm. The same bike with the same fork in 20-21 came with 4.0N/mm The 22-24 bike was 4.4N/mm. The forks are all xplor forks, but with different valving. Most have revalved and converted the forks to full open to fix the Xplor fork wacky compression side orifice with a midvalve and base adjusters. Then what chart do you use for a spring at your weight?
Racetech is a good resource but there is always room for tuning. I do enough suspension that I know what spring rates to use for what weight/style and if I’m unsure I ask Stadium suspension or GP Moto.
No. There are 2 major problems with them. They push the intake boot back so it kinks & at low intake velocities (low rpm) the fuel pools in the intake causing a low end bog. I have the TSP IRK which performs very well but is MUCH more finicky to tune. For the majority of riders I think installing a TSP map is the best option & leaving the injectors stock.
@@ChuckfromTrueTechjust to add info to this. I run the dual relocation block. With a stock map yes it pools and you have to rev the shit out of it here and there to clear it out. But after an ECU tune ment for the mod I've had no issues with my lower end and have a very crisp bike for much cheaper then the full tsp kit. I didn't have the money after buying a brand new bike (XCW 2022) for tsp and went out on a limp with best dual sports products. Really can't complain after all the heachaches from stock and I ride very technical mountains in Pemberton BC.
@@SnakingIvY I have 2022 ktm 250 exc tpi and I dont seem to have any of those pooling issues. I can leave it idle for 5 minutes and go ride with no issues. Also I can lug it the same as before except now it has more torque which is better. Everything is stock except that dual relocation block.
These videos have been great, super informative and provides a great prospective on suspension!
Love these and everything about this channel! You’ve been so helpful and generous with your information and knowledge. Thanks.

Hey Chuck, what's your go-to brand for shock bearings/bushings? Do you usually go OEM or something else?

Are you familiar with tpi injector relocation block which moves both injectors? Do you think its worth it for my 2022 ktm 250 exc tpi?
No. There are 2 major problems with them. They push the intake boot back so it kinks & at low intake velocities (low rpm) the fuel pools in the intake causing a low end bog.

@@elkku2140 Hm perhaps the exc has a different map. I know my brothers gas gas also does not have nearly the same pooling issues as mine did.
@@SnakingIvY that might be it
