Does a ktm 300 have a balancer?
Just googled it, they just started using them in 2017
Hey all, desert season is here and I've got the quad finished up (well, 99% of it anyways).
Took some lessons from last year riding it and made some changes. I reworked the radiator mount, brought it higher up and closer in, and ditched the heavy steel guard I made. It'll be getting a light honeycomb cover circle track racers use.
I put a +4 swingarm in it with a banshee axle. I wasn't ready to put on hydros so I modified the caliper to float so it'll work with the new axle/brake hub. I also added some gussets to the frame below the front engine mounts.
I need some new dirt tires for it, and my new pod air filter to come in, but aside from that this thing is done.
I'll try and get all the pics posted here updated, not sure why most of them died.
Nice job !! I bet that will embarrass many quads
Do a search on "frame gussets" there's other places that could (and should) be gusseted.
I'm not much of a structural engineer but I'm not sure where else sees much stress? The rear is already stout for the swingarm, the bottom mount is a full width C channel bar with vertical tabs, and the front mounts have 2"x1/8th" plate gussets down to the lower frame rail.
Probably find in the first link

Bit of an update for you all..
Quad is running like a boss. On a recent trip I actually broke the front radiator off, decided that wasn't a good fit on the quad and grabbed a set of original radiators and grills. Shoehorned them under the front fenders, somehow. Haven't had any issues with that since. I do need a hood now that the radiator is gone. Someone wanna sell me one?
Got some new rubber as well as upgraded the rear hubs to banshee/raptor 660 hubs to get that sweet common 4/115 bolt pattern.
Got a desert trip planned again in the next couple weeks so I'll grab some gopro footage for you all. It's a ripper.
At the time of this post the quad is functionally finished! I went over to Abla (They're local to me) and got a +3 +1 A-Arm kit for it. That widening kit was beating me up bad.
Since the last post I added along with the front end a head stay mount to hopefully help spread some of the vibrations to the rest of the frame. It's single sided since the fuel tank extends lower on the right side, but it's very strong.
Total mod/parts list:
TSS +4 Swingarm
Raptor 660 rear hubs
Raptor 660 Front Bumper
Floating caliper mod for banshee axle swap
Alba +3 width +1 forward A-arms
Honda 400ex rear shock
Honda 400ex front shocks
45 Watt Stator from regulatorrectifier.com
1998 YZ250 factory radiators
2x HPS stainless T-Bolt clamps for a HPS high temp silicone exhaust coupler
Overall, I love this quad. It weighs nothing, it's fast, and being 2 stroke it's easy to fix. If I were to do anything more to this, it would be to upgrade the engine to a newer year so I have access to the 300 big bore kits.
