Have the battery tested. 12.4v is a little low and these machines rely heavily on a good battery.
As said a possible faulty alternator also as this will take the battery down with it 👍
Wow, that sounds like an adventure dude, suspension, brakes and all kinds of but to deal with the extra power and stopping power.
You'll have to keep us updated with the info on how you get on and most of all, how this machine turns out and goes🫵😎👍
I used my 38' to stomp up to a village to give a cheeky girl my number who then gave me hers without hesitation 🤩
That was scary🤣
Then it'll go shopping with me on the Saturday ritual 😵
Have you checked the roll bar bushes as well?
A simple test to look for other issues is to brake sharply at a low speed and wait for a "thunk" from the front end.
This usually points towards the lower suspension arm bushes over compressing and allowing the alu arm to come to an abrupt stop...
Yip, approved theory my mate.
I get around 40k miles from my 38's tyres and they are starting to micro crack... It's time for new ones even though there is still a decent bit of tread left.. 🤔
OH the choice🤷
