These comments came from my replies to someone trying to switch over from a carby 125 to efi 125.   Use these words as some kind of wisdom if you like as the 650 may have a similar principal.  Also it is possible and easier on 650 than 125 but time , effort, lots of money plus the fact carby is more reliable than EFI due to less electronics in…[Read more]

Hey Nathan, yes if there the same shape seat. Just don’t fit new gen seats that’s all!

Frame Tap = Tap that is mounted on the left side of the frame and it has ON/OFF/RESERVE markings on it. GTR bikes use vacuum taps since they entered the market. Later GT nakeds switched to vacuum taps on their new shape bikes

The 250 clutch does start to wane a little beyond 3000km ish but ive seen people ride beyond that. The manual does say inspect the WHOLE clutch every 4k.
Tap the link below , which is a tutorial and read where it says SYMPTONS.
Hard neutrals is one of them listed there.

Motul Ester or Silkolene ESTER (Note the ESTER), is the best oils for the…[Read more]

It’s okay, the site has a contact page for sales enquiries.

Contact

If no one else has sent you a PM,

Send me an email.,  I may try to get this new one off the trade for you.

Have you searched or browsed the forum.  There was a discussion about this.  If you cant see it, I will try to find it when i return back.  it wont be easy but patience.

I can only say PLEASE do not stress the manifolds. They are very very hard to buy these days.

Send me an email, with pictures or attach on this forum reply box

1. Your handle bar, and i want to see the steering mount bit where its cracked off.
   I may be able to supply you just the SOLID BAR without mount, as you can unscrew your old broken bar out of the fork mount.   Pics help first.
   The bar sold is 100% identical to OEM one, my CNC guy j…

How about the other 2 points above ?

In regards to the carb, I don’t know if you can but can you take out spark plugs and  upload on this site ? (Add media button on the reply box)
We can see if its running rich and which cylinder front vs rear.

I rarely encourage messing with the air mix screws for many reasons unless a pro is good with…[Read more]

Welcome to the site and happy holidays

It would be useful if we know these (makes troubleshooting whole lot easier) , if we skip these , i won’t know how to answer accurately. History helps.

• Total miles on dash?
• Has it had valve clearances done? (can’t be avoided)
• Has it had its carbs taken apart and blasted clean (via air compressor,…

BTW have you recieved my email? Its urgent.

In regards to your bike, how good is your battery? (Did it get garage tested. They have special meters).  Id start here first.

After, have you taken the tank off. Used contact cleaner to clean ur plugs every where (gold pins can turn rusty from oxidization / winter road salt) its harder for electrics…[Read more]

Something like that. But a wide box similar to OEM cause that in pic^ is too damn small.  But you get the gist.

3rd hole is just to link tubing to the side from box(where oem filter is)

See that it has a hook hole?

A bolt goes through it. Then screws to metal hinge thingy thats on the GV frame (weld one on to it).   Creativity ideas th…[Read more]

You can however…..

Make a metal box with 2 holes under it. Then rubber gromets for the carb to slide in to the box.

A full welded box but its narrower to clear the frame. Enclosed unit like the plastic oem box.

Extra hole at the front that allows a BIG flexi pipe to the front right mini oem air filter box.

There. We just remade the top…[Read more]

I forgot the exact dimensions but you are right to say even a few mm off make a difference.  I know that the Hyosung Carb is based off BDS26 BUT… it doesnt use mikuni part numbers ,  notice on your own parts list.  The numbers are OEM based.  So Mikuni makes certain parts spec’d to Hyosung  while the empty skeleton body BDS26 is generic and used…[Read more]

No matter what Alan, I’ve tried everything, the box just wins.

The poster above you says he had to “un-cone”  (basically go back to as stock as he can) then the bike responds better.  Not the engine’s fault but the nature of the CV carb has made sure it wants a box not for air flow, also air pressure and other science.   Pods just run too wei…[Read more]

Following this closely.

Sorry that this wasn’t auto-approved a week ago, I am going to completely overhaul the site once again so it is less strict , trust me it is starting to annoy me now , but there is no excuse for a developer as myself to fix things , life got in the way!

Nice to see you Scott!

Around 1.5 to 2.5 turns on the GT250 but caution this because KR didnt reveal it and heavily discourages messing with the mixtures. And also caution that rear engine likes to run a little richer (a little).  hence the 2.5 step staggered fashion of jetting KR did for the 125 and 250 models.

In your pic. Yes it is a breather / overflow to the…[Read more]

This happens, usually replacing the fuel gauge seems to fix it especially on dashboards that have white or orange display LCD.  Also the dash reads the level sensor directly, so check the harness from the dashboard plug going to the tank level sensor plug.

Hi, sorry I didn’t reply so soon!
Did you get anywhere then?

I assume you have had a digital meter on the coils , stator unit, plug caps? Other things that cut off sparks are “stand switch,  clutch lever switch, cdi unit, neutral sensor” have you checked those too.

The mystery diodes & igniters embedded in the harness don’t usually just fail,…[Read more]
