hi guys. thanks for the replies, appreciated.
I use medium compound grips, i don't like soft, there too sticky and hard compound just hurt bad.
my grips are a few weeks old too.
I usually get arm pump for my first practice for a few mins then i don't get it again. but my hands hurt really bad every time i go out, to the point i can't pull in my clutch cause my fingers are just frozen and numb. it basically means I can only do 3 or 4 laps and thats it. it's all over.
Maybe it is my grip but i do try and take care not to grip too hard. also i've only suffered this since i moved onto a 250f. i've always been on 2 strokes which i've never really had any probs with.
also, as part of my training i use hand grippers/squeezers. i don't use them a lot but when i do within 1 minute of doing it, it hurts my hands bad. the pain always seems to stem from the base of my thumb/ ball of my hand and then the pain just engulfs my entire hand.
