I disagree, my local Motorbike shop have been going 40+ years, they have experienced mechanics that are passionate about all sorts of motorbikes, including drag and superbikes. You've just got 'Sh@*ty' shops near you.

Have a look at my 265 thread, I go through the clearances required with an ARC rod and NR racing 274 cam. You can see in the video how easy it was to address. D

Your local motorbike shop will be able to advise and probably have the chain in stock, I've used all sorts of chains and realised you get what you pay for.

Remove the low oil sensor, these are designed for stationary use, when used on mobile stuff ie. go kart the oil sloshes around and cuts out the engine. If you don't want to open up the engine, then just re do the wiring on the front near the engine on off switch, you only require the on off...

Some more time spent in the workshop. The exhaust has been fabricated to suit the silencer and fitment to the go kart, I need to get a feel for the correct depth of the O2 sensor before I weld in the bung, the exhaust is only 34mm. The forth bearing support has been a fair amount of work, I...

Too much fuel delivery is more of a problem than not enough with a pulse pump, better to take the pulse from the intake adapter because it's clean air as shown in thepartsguy's photo. The billet side cover barbed fittings provide extra breathing for the engine, these two lines go to the rocker...

I hope you're getting confused between the governor assembly and the compression relief/ezi start mechanism. If you have removed this, then buy another cam, never remove this unless you're in full race mode and have an external hand held electric start. The compression relief allows an easy...

No compression release?? The compression release is on the camshaft drive sprocket. Check for any air leaks, blocked jets, correct valve lash, if all good, it's a matter of patience setting up with different jets. The guys on here should give you an idea about the best carbs for the 212

Zendesk is used in the UK by large International retail companies, AI is part of the 'virtual' assistant on live chat, I've had to deal with this several times, really not sure about it, still prefer speaking to someone at the end of a phone.

Here we go, the crank has been balanced for the new billet parts to the tune of around 6000rpm. No idea whether this will really make any noticeable difference to the vibration of the engine, we'll see when it's running

I'm building a 265 out of a 224 Ducar/Predator engine, the 224 block makes life sooo much easier for any mods. It's braced and clearanced, all std components fit, great starting point. Get a 'road race' cam, flat top piston, 16lb springs, a little port work to the head, basic exhaust tube...

Stationary engines now have to comply with emissions, one being fuel vapour, some newer engines breathe fuel vapour through a charcol cannister. Blow through the broken tank vent to see if the fuel cap is vented, if not drill a 2mm hole in the centre and block off the breather pipe to the air...

What sort of power increase % is expected from using a supercharger, it's obviously been done a few times. How do you get over the parasitic forces absorbed by the supercharger when attempting to drive off, is this where a cvt has to be used? An interesting thread worth keeping an eye on

There's a hydraulic dyno DIY build on youtube, General hydraulic pumps don't like to turn too fast, you can run the hot fluid through a standard cheap radiator. I was thinking of a simple hydraulic dyno, then I saw a video of a dyno using a lorry wheel setup, the advantage of this is a massive...

Just went out on a job this morning, the Company that manufactured the gate used 'budget chain' this snapped we got a phone call, we repaired, we said thankyou very much££££ customer a little poorer but happy. I used to work for the company that made the gates, when the wrong person ordered...

Welding is part of my job, I'm out on site most of the time, £500 helmets are a waste of money due to possible damage. ESAB are a trusted and well established brand. The Clearview is a step up in Autodarken technology. The battery is a back up to the solar and only used for low light...

ESAB savage A40 clearview, fantastic helmet. One battery in 5 years.

TSUBAKI, Japanese quality chain. Our industrial transmission supplier won't stock cheap chain. You get what you pay for. Used this chain on my modified GX390, never had any trouble with it.

If you want to improve the engine for little extra power for minimum $ then: Get yourself a cast Ali flywheel and some offset keys for timing, non hemi engine uses the same GX standard taper (apparently) Gas flow the head, or just buy one already done, If you do it yourself, it's only really...
