If the LiPo-Battery has got a BMS, make sure your regulator is not set to some stupidly high cut off voltage (some old regulators go up to 14.8 to 15V to de-gas lead acid batteries) and other than that: you already have a LiPo usable regulator. LiPo-packs w.o. a BMS are a bad idea for vehicle...

Make sure you have the right spacers for the forks. I recall at least Wilbers used to ship them with very different (i.e. longer) spacers. Also you had to state your weight and they would match the springs for you.

Regarding the Dell'ortos: The old (German) TR1 racing crowd is split 2/3 to 1/3. The bigger group thinks they are the best thing since sliced bread and quite frankly there's some pretty good recipes out there from Sepp and the others , which will get you to a bike that runs a lot better than...

Yes, the taper they have on the air-screws is stupidly steep... but it's the same problem on the VM38s, which is why I adjusted them with a wideband - just too heavy handed to make them work decently any other way.

Add the correct springs, check the pre-load? TR1 forks, if anything, are very much on the stiff side with progressive springs, if I am honest...

That is quite a long intake for this engine and carb combo. It will work, because large displacement fourstrokes are stubborn beasts, i.e. they create a lot of vacuum at low rpms anyway. Are those the 43 or 47mm OD TM38s? If they are the 43mm carbs, you could go with VM38-200 inlet rubbers and...

Absolutely love this.

Let's just say the last three years included a move, two sidecar builds, finishing a degree at uni and lots of other stuff, but: https://www.youtube.com/shorts/Y0nnOAdB4w8 or a bit more obvious https://www.youtube.com/shorts/vg-fMK730TM Guess you'll read a bit more about it in the near...

I haven't noticed anything rust-related in any of my fuelt tanks, so from an engineering viewpoint I totally agree, in practice I wasn't able to witness any conclusive results though...

Ethanol is your friend. Your new best friend. A friend with benefits so to speak. Its knock-retention capabilities vastly outclass all the compounds that were before it. Ethanol itself is not much a problem if you drain your carb(s) once you plan to park the bike longer than a week or so. (I...

Do yourself a favour, especially with a bike, which in comparison to what the Velorex was designed for is so powerful and convert the mounts to ball-head clamps and the rear mount to a sliding mount inside the frame tube. (Design was intended for a 12 to 18hp motorcycle...)

Hahaha, you flyweight - there's a reason, why I am tuning XV1000s with similar ideas. *cough* trying to get below 90 again... (but also slightly bigger) Btw.: Fell over your 95 vs. 98 question - I personally aim to be able to run an engine on 95, because if you get into knock-territory, you can...

Mr. Loek, from one TR1 engine builder to another... why go with the XV1100 crank and modify it, if you could have gone with a BT/XVS11 crank? Works look superb, regarding the 100mm pistons... lovely work, especially the hemi-conversion of the heads.

Personally I think those Chinese carbs aren't too bad. But a wideband AFR and a dyno (or at least which you can drive up and down 100 times to check against the changes you just made), will come in very handy. Also there's unbranded Chinese carbs, which I would stay away from and then there's...

Guess we all tend to go to the same places...

Maybe we should actually revive it... Not really feeling at home here or on brand-specific forums and the different ideas were always very inspiring.

As it has still got the Rayjay fitted, are you planning to run this or upgrade to a ball-bearing turbo and if you're sticking with the RayJay, how do you plan to increase the oil-pressure for the turbo? (Or how has it been implemented in the past?) Hold on a sec - is that you Mr.B from the old...

In the end I bought a 6x26 mill instead.

I am one of those guys from back in the day and I found 137.5 with pods to be even better. My high-flow exhaust was a very rotten stock item that may or may not have the lost the odd baffle due to rust eating it away. Also be aware, there's Mikuni and Keihin carbs on those T300-Triumphs...

You can fit a bigbore piston and alternatively you can fit an XT250 engine... That's pretty much your only options for simple alternatives
