Hi,
I installed the 92.5 and 90mm jets after putting on the Leovince silver tail exhaust and it bogged out and wouldn’t go past 30, I think it’s to many sizes up, would it be better on a 86/87mm.
also the cdi unit on the hyosung gv125 (2016 and before) has a ristrictor for emissions restricting the mid and top range acceleration is there a way round this? Do people sell/modify these? Could I do it myself?
thanksharry
So exhaust plus carb jetting clean and balancing after exhaust is on about 1.5 hp ?
Also compared to stock is the leovince heavier ?I know I’ve asked the same question about the front sprocket before but for example is a 14t or a 15t light enough.
Hi
The sprocket kit is installed but has a 12t sprocket on the front can I change that higher or to much weight for the engine ?
is there an uprated air filter for the hyosung gv125 beacuse I’m installing the higher mm main jets ?
I’ve just ordered a Leovince silvertail exhaust does this add any performance to the bike other than a better sound no hopes just curious.
many thanksHarry
Hi
do you know where to get the carb jets from ?
Sprockets worked well, consistently hits 70 and above.
also is there anything like a big bore kit, I know it’s a long shot however would be cool.
thanksSorry, correction the bike has a stock exhaust
yes Leovince is very pricy I saw a tk custom exhaust for the gv 125 for 240 but I can’t source it reliably do you know of any brands that make a cheaper one ? Or is Leovince the best and only?
hi
I don’t have a exhaust at the moment but was looking at the ko2 Leovince silver tail they look good,
The jets 90 on the front 92.5 on the rear cylinder right ?
I’ve already upgraded the swing arm plates as they bent the first time it was adjusted never done it since they were replaced
both rear bearings have been replaced aswell beacuse they were rusted factory never put the rubber seals over the opening on both sides
with the clutch is there a performance outcome or is it solely comfort I did see a clutch overhaul kit but I haven’t noticed any slippage so does it need it ?
final question, the wheels are quite heavy is there any lighter wheel sets, I doubt it beacuse the size is quite hard to come by but was wondering
Hi I was wondering if there is any way of squeezing more top speed out of a 2016 hyosung gv 125 I have put a 52 tooth sprocket on the rear and looking at a 16t sprocket for the font but is there any thing else I can do to it eg different jetting in the carbs or is there any ristrictions within the motor? I spoke to a machanic who said any tuning wouldn’t be worth it and it would more than likely blow up, is this the case?
Bike has 5000 miles valve clearances we’re done 200 miles ago spark plugs amber Color so engine is fine full service 350 miles ago
